Glue a plastic bottle onto a wooden base. Place the mountain-shaped chicken wire over
the bottle and cover it with paper strips dipped in glue made by heating and stirring a
flour and water mixture. After a couple of days when it is dry, paint it like a volcano
(lots of streaks of red, yellow, brown and black). Place two teaspoons of sodium
bicarbonate (also called baking soda), a few drops of red food colouring and lastly, some
vinegar into the bottle. Watch your volcano erupt.
